You can also just buy the evaporator unit from Vintageair. That is what I did.
By the way. It is not a switch. It reads the high side pressure. Then in the tune you have tables that allow you to turn one fan on and off at one set of pressures and a second fan on and off at another set of pressures. Keeps the fan use to a minimum. Of course the system would run fine without that.

I use a "differential type" trinary to trigger the fan relay "on" at 250psi & "off" at 200psi of head pressure.
I have a question....How are you guys sending a A/C request to the PCM without the factory control head? Or does the factory "pressure transducer" signal turn the fans on/off based on pressure, speed etc., without a A/C request?
